Design And Development Of Eportfolios System

Consummates the evaluation system's request based on the new curriculum reform, eportfolios the achievement implements the new curriculum reform the process evaluation one kind of effective tool, already gradually obtained by educators. And lifelong studies along with the study society's construction needs, eportfolios will become the network time the essential, it not only as appraisal method and tool, moreover developed into one kind of study tool and the support environment, had functions of knowledge management,cooperation study,multi-dimensional evaluation and so on. After the author having studied the domestic and foreign some eportfolios system, summarized these system's deficiency, refered to the author's understanding, and acted according to the current computer network, the database technology development condition to analyze the development eportfolios the feasibility, the ultimate design and developed has been possible simultaneously to face the teacher and student's eportfolios system. And has realized the function which basically the design requests. Including 4 parts of onstage user interface,manager subsystem,teacher subsystem and student subsystem.At first this article introduced eportfolios' domestic and foreign related research, the development of present situation and the researching significance, explained the development eportfolios system's rationale and the correlation technique, elaborated eportfolios system's analysis and the design in detail, has carried on the detailed explanation to overall system's each functional module. Described the process of system exploiting, introduced system's design concept, the technical route, develop the function which the platform the choice, the system overall frame, the operation flow, this system should realize as well as concrete realize the method and the step. The author based on the software engineering in waterfall model's development thought that has completed this system's design and the development. In the system realizes in the process, mainly has used the ASP technology, the XML mark language, the VBScript script language, the CSS cascading style sheet and so on commonly used network development technology, has used B/S (browser/server) the architecture, enables the system to have may entrust with heavy responsibility with the maintainable good characteristic. The system use's essential programming technique including the classification and the label, the fuzzy inquiry, the RSS Really Simple Syndication, the MD5 encryption, SQL pours into filtration, confirmation code and system buffer technologies and so on.Final, to make a system texting, through the testing, may guarantee system's normal operation. And completes to this article the prime task has made the summary, proposed the research deficiency as well as to the next study and the work study forecast.
